Description product group

Electrochemical combination electrode: pH and reference electrode integrated
The large dirt-repellent Teflon^® diaphragm prevents the reference system from becoming blocked up
Long service life when solids are present
High-viscosity electrolyte combined with a salt reservoir prevents the electrolyte from 'bleeding'
Long service life without drifts when there is clear water with low conductivity
Twist protection for the sensor cable connected. This means that the cables can remain connected during installation and dismantling of the sensor, avoiding troublesome moisture on the connector contacts
Lead-free glass for advanced and environmentally-friendly production, use and disposal (RoHS-compliant)
